A new tab integrated into the JetBrains YouTrack mobile app that lets any user describe an idea in plain language, generates the full project with Junie AI, deploys it on AWS, and pushes it to GitHub — all without leaving YouTrack.

YouTrack is where developers manage their work — but when it's time to actually build something, they have to leave the app, set up a local environment, install dependencies, configure cloud services, and create repos manually.

JetDev closes that gap. From the same app where you track your issues, you can now spin up a fully working project in the cloud with a single description.

1. Open the new "JetDev" tab inside YouTrack mobile
2. Describe what you want to build in plain language (guided conversation)
3. Junie AI generates the full scaffolded project — all compute happens in the cloud, zero local resources used
4. AWS deploys the app remotely and streams a live visual preview back to the mobile screen
5. You review the running result directly inside the app — no install, no local server, just a visual preview rendered on-device
6. Accept or Discard the result:
   • New project → Accept creates the GitHub repo + initial commit / Discard destroys the environment with no trace
   • Existing project → Accept commits only the new changes to the existing repo / Discard rolls back to the previous state, nothing is overwritten

The interface replicates YouTrack's existing mobile design language:

• Navigation: Follows YouTrack's left-hand vertical panel pattern, adapted for mobile bottom tab bar
• New tab added: A "☁️ Dev" tab appears alongside Issues, Boards, and Articles
• Design fidelity: Colors, typography, card components, and interaction patterns mirror the current YouTrack 2025/2026 design system
• New screen flow:

[ YouTrack Bottom Nav ]
Issues | Boards | Articles | ☁️ Dev  ← NEW TAB

      User decision:
      ✅ Accept → GitHub repo created + code pushed
      ❌ Discard → AWS environment destroyed, nothing saved

• Node.js >= 18
• React Native environment set up
• Junie CLI installed:

  curl -fsSL https://junie.jetbrains.com/install.sh | bash

• AWS account + credentials configured
• GitHub personal access token (repo scope)
• OpenAI API key (provided by HackUPC JetBrains challenge)

Create a .env in /backend:

JUNIE_API_KEY=your_junie_key
OPENAI_API_KEY=your_openai_key
GITHUB_TOKEN=your_github_token
AWS_ACCESS_KEY_ID=your_aws_key
AWS_SECRET_ACCESS_KEY=your_aws_secret
AWS_REGION=eu-west-1
PORT=3001

cd backend
npm install
npm run dev

cd mobile
npm install
npx react-native run-android   # or run-ios

Request:

{
  "prompt": "I want a REST API for a restaurant reservation system with authentication"
}

✅ Done!

Final payload (after generation & deploy):

{
  "status": "preview_ready",
  "previewUrl": "https://my-app.amazonaws.com",
  "jobId": "abc-123",
  "stack": "Node.js + Express + PostgreSQL",
  "nextSteps": [
    "Add payment integration",
    "Set up email notifications",
    "Configure custom domain"
  ]
}

The mobile app renders previewUrl in a WebView — the user sees the running app without any local compute. All processing is on AWS.

On user action:

POST /accept/:jobId

• New project → Creates a new GitHub repo + initial commit + push
• Existing project → Commits only the new changes on top of the existing repo

POST /discard/:jobId

• New project → Destroys the AWS environment, nothing is saved
• Existing project → Discards the new changes, repo stays as it was before, environment rolls back

Returns the current status of a running generation job.

This project directly addresses the "Help the Developer" challenge by JetBrains:

JetBrains tools used:

• Junie — core AI code generation engine (headless/programmatic CLI mode)
• YouTrack — host app, design system cloned for the new screen
• OpenAI API — provided by JetBrains for the challenge, used for NLP onboarding
